10 Leading ZnS Suppliers in the world 2025

Introduction to ZnS

Zinc sulfide (ZnS) is an important inorganic compound with a wide range of applications. It exists in two main crystalline forms: sphalerite (cubic) and wurtzite (hexagonal). ZnS has excellent optical properties, such as high refractive index and good transparency in the visible and infrared regions, which makes it a key material in the production of optical components like lenses, windows, and infrared detectors.

In addition to its optical applications, ZnS is also used in the field of luminescence. When doped with certain impurities, it can emit light under ultraviolet, cathode - ray, or X - ray excitation, and is thus widely used in fluorescent materials, electroluminescent displays, and scintillation counters. Moreover, it serves as a pigment in the paint and rubber industries due to its high hiding power and good chemical stability.
